The Olympiacos defender suffered the injury to his left knee in the 37th minute of the tournament's opening game in an innocuous-looking challenge with Poland striker Robert Lewandowski. Papadopoulos tried to play on, but had to be replaced.

A statement on UEFA's official website read: "Scans confirmed the 27-year-old suffered a torn anterior cruciate ligament and sprained lateral collateral ligament of the left knee."

Papadopoulos has returned home for treatment. Greece's next Group A game is against Czech Republic in Wroclaw on Tuesday.
